Moscow -LRB- CNN -RRB- A Russian TV channel aired Hillary Clinton 's first campaign video with a rating stamp that means it 's for mature audiences , because of fears it might run afoul of the country 's anti-gay propaganda law .

A clip of the video , which features a gay couple holding hands , got the 18 + rating from the independent TV Rain channel in Russia on Monday .

The channel told CNN that it did n't want to break the controversial law , which bans `` propaganda of nontraditional sexual relations around minors '' and bars public discussion of gay rights and relationships within earshot of children .

`` There are no legal precedents for this law , so we just do n't know what comes under this law and -LRB- what -RRB- does n't , '' a TV Rain spokesperson told CNN .

`` Therefore , fearing to break the law -- especially given the high attention to TV Rain from the supervising authorities -- we decided to put a marker -LRB- on the video -RRB- . ''

Clinton 's video was released over the weekend to announce the start of her 2016 U.S. presidential campaign . It features about five seconds of two men holding hands . One of the men says , `` I 'm getting married this summer to someone I really care about . ''

The former senator and first lady first declared her support for same-sex marriage in early 2013 , saying that `` gay rights are human rights , and human rights are gay rights . ''

Russia 's controversial law caused an international outcry after it was passed by the Russian Parliament and signed by President Vladimir Putin in July 2013 .

Human Rights Watch described the anti-gay propaganda law as `` a profoundly discriminatory and dangerous bill that is bound to worsen homophobia in Russia . ''

Rights campaigners called for a boycott of the 2014 Winter Olympics in Sochi , and a number of bars around the world stopped serving Russian vodka in protest .

U.S. President Barack Obama -- Clinton 's former boss -- said at the time that he found the legislation offensive .

`` I have no patience for countries that try to treat gays or lesbians or transgendered persons in ways that intimidate them or harmful to them , '' Obama told Jay Leno in 2013 .

Putin defended the law , noting that unlike other countries , Russia decriminalized homosexual relationships -LRB- in 1993 -RRB- .

`` We do n't outlaw anything and do n't nab anyone , '' he said before the 2014 Games . `` That 's why you can feel safe and free here , '' he added , `` but please leave our children in peace . ''

The rights group ILGA-Europe said in a May 2014 report that Russia was the worst place in Europe -LRB- out of 49 countries -RRB- for LGBTI people to live .
